I think a while ago DamageX, our american MSX-friend, somehow upgraded amount of memory in his S1985-based MSX-2 system. I tried to find the thread with information, but failed. DamageX, can you please help me with info? We can chat via ICQ/GTalk/MSN/IRC or any other means you prefer. I would love to upgrade my revived Sony HB-F1 from 64K to 512K, or even more!  |

I found the thread for you, by searching for 628512
http://www.msx.org/forumtopic5569p15.html
I did stick a 74245 in there later on, to hold that one keyboard line low during reset so that the 512KB is always enabled. BTW, 512KB is the maximum when using the mapper in the S1985 since it only uses 5 bits. Let me know if you have any questions. |

I do have 4MB memory mapper from Leonardo, but it's no fun at all. I like to play my game in one slot with gamemaster in the other.
